What is Arnold's last name? (of "Hey Arnold!")?!
Arnold is a fictional character in the Nickelodeon animated television series Hey Arnold!. His head is shaped like an American football, thus earning him the nickname Football-Head.Throughout the series' run, he was voiced by at least five different voice actors: J.D Daniels (who did his voice in the pilot), Toran Caudell, Phillip Van Dyke, Spencer Klein (who did his voice in the movie), and Alex D. Linz (who did his voice in the last two episodes of the series).
It doesnt say anywhere. Sorry
He doesn't have a last name, it's just Arnold.
Ive been looking for his last name too.
I used to watch that show, and I don't think they ever mentioned it.
Arnold Shortman would be his name :)
